Product Description

The UDX-G11/-12/-13/-14 are single-ended pulse heads used for high-resolution TDR/TDT measurements in concern with the UDS-2214 sampling oscilloscope. They provide fast pulses having both positive or negative polarities, rise time of 100 ps and flat transient response.
The UDX-G11 and UDX-G13 are TDR/TDT Loop-through Heads having 400-mV pulse amplitude, while the UDX-G12 and UDX-G14 are TDT Heads having increased 2-V pulse amplitude.
Different configurations of the heads provide single-ended, common and differential TDR/TDT measurements.
Normalization as an error-correction process is available. It helps ensure that TDR and TDT measurements are as accurate as possible.

TDR Normalization
UDX-G11 Head:
The top waveform shows distortions caused by cables and
connectors with reflected rise time of 202.5 ps.
The bottom waveform shows how normalization corrects for
these distortions. Normalized rise time is 101.6 ps.
